0: SPI is disabled.
1: SPI is enabled.
0: As soon as data is written in TDR.
1: TDR and internal shifter are empty. If a transfer delay has been defined, TXEMPTY is set after the completion of such delay.
0: No rising edge detected on NSS pin since last read.
1: A rising edge occurred on NSS pin since last read.
0: No overrun has been detected since the last read of SR.
1: An overrun has occurred since the last read of SR.
An overrun occurs when RDR is loaded at least twice from the serializer since the last read of the RDR.
0: No Mode Fault has been detected since the last read of SR.
1: A Mode Fault occurred since the last read of the SR.
0: Data has been written to TDR and not yet transferred to the serializer.
1: The last data written in the Transmit Data Register has been transferred to the serializer.
TDRE equals zero when the SPI is disabled or at reset. The SPI enable command sets this bit to one.
0: No data has been received since the last read of RDR
1: Data has been received and the received data has been transferred from the serializer to RDR since the last read of RDR.
